testControl II – the Innovative Electronics

Powerful, innovative measurement and control technology

testControl II measurement and control electronics provide the ideal basis for precise, reproducible test results. As well as setting new standards in safety technology, efficiency and quality, testControl II is laying down a benchmark for drive technology.

Key Advantages and Features

testControl II impresses with its high measurement speed and accuracy, flexibility in use and fast control characteristics.

The combination of powerful, flexible measurement and control technology plus an innovative operating concept guarantees an optimum solution for testing applications, from the simplest to the most demanding.

The high-quality finish protects the testControl II measurement and control electronics from external influences. The components used are highly durable.

On static materials testing machines the testControl II measurement and control electronics are mounted vertically on the load frame for better protection against ingress by liquids or conductive particles (dirt, dust, liquids (IP 32), vibrations).

High Measuring Accuracy and Reproducibility

Maximum Accuracy

High (24-bit) resolution and A/D converter with 400 kHz sampling rate for maximum measured-value accuracy combined with large measurement range. As an example, even the smallest force changes on the specimen can still be recorded and displayed accurately.

High Data Transmission Rate

Synchronous 500 Hz measured-value acquisition-rate delivers fast measurement with maximum reproducibility (regardless of number of measurement channels). The measured-value acquisition-rate can optionally be increased to 2000 Hz. The high data transmission rate enables fast measurement with maximum reproducibility. This is highly advantageous for high-speed tests, short brittle-fracture events and in tear-growth, adhesion and peel tests.

Time-Synchronous Signal Processing

Time-synchronous acquisition of measured values from all sensors connected to
plug-in slots takes place at the fast system-frequency, as does data transmission to ZwickRoell
Roell testing software. This ensures high test-result reproducibility regardless of the
sensors in use or the test sequence; for example force and travel signal synchronicity is
maintained, even with strongly differing test speeds.

Ideal for tests for which direct-measurement extensometers cannot be used.

Eco Mode

testControl II electronics switch automatically to eco-mode when not in use, saving energy.

System Monitoring

testControl II system monitoring provides the user/laboratory manager with detailed information on the current status and level of utilization of the testing equipment. This enables further increases in testing equipment availability and greatly simplifies maintenance planning and spares/replacement procurement.

Powerful Drives and Drive Controllers

Fast, Adaptive Drive Controller

The high drive control frequency of 1000 Hz delivers fast, precise force and strain control. Benefits include enabling components to be loaded very quickly and accurately with a predetermined force.

Strain Rate Control

The AllroundLine drive technology’s excellent constant-velocity characteristics and interaction with the sensor technology and adaptive control make it ideal for demanding strain-rate control (e.g. ISO 6892-1, Method A1).

Controller Setup

Special controller set-up for testing situations with demanding control requirements. For example, if the force sensor is located on the fixed crosshead in force-controlled tests, the controller can simply be switched in the software.

Powerful Drives

Powerful drives allow cyclic tests to be performed at maximum speed up to nominal load - with no waiting time between tests. AllroundLine and ProLine use maintenance-free AC drives.

Flexibility Through Modularity

Flexibility Through Modularity

testControl II has six flexible time-synchronized slots, allowing multiple sensors to be used simultaneously and monitored and safeguarded regardless of use.

As an example, an extensometer and a transverse strain extensometer can be used in addition to the load cell.

If the testing system is equipped with several load cells or additional sensors, these can all remain plugged in. All sensors which are plugged in will then automatically be protected against overloads.

Innovative Interfaces

The innovative EtherCat® interface is incorporated as standard. The time-synchronized real-time Ethernet field bus system ensures future-proof integration of sensors and power units.

testXpert Research software is designed for dynamic tests in conjunction with testControl II electronics. Integrated software for the entire test sequence guides the operator step by step through parameterization of the controller, the test sequence and result evaluation.
